Invalid JSON file with multiline commit message

[jslee02]

When I try to upload JSON file generated by CoverallsGenerateGcov.cmake script, I get the following error:

{"message":"Couldn't find a repository matching this job.","error":true}

It seems this happens when the git commit message is multiline. Here is an example JSON file with multiline message:

  "git": {
    "head": {
      // ...
      "message": "Merge pull request #123 from some/project  

Pull request title with multiline comment"
    },
    "branch": "master",
    "remotes": []
  }

Since JSON doesn't allow real line break, this file is not valid one.

One possible solution I can come up with is replacing \n with \\n so that the message include \n instead of the real line breaks as:

  "git": {
    "head": {
      // ...
      "message": "Merge pull request #123 from some/project\n\nPull request title with multiline comment"
    },
    "branch": "master",
    "remotes": []
  }
